To all whom it V :7

Be it known thatgEnivA'nn A, Summer, a citizen of the Unlted States, residin at Chicago, in the county of Cook and tatc of Illinois, have invented certain new and useful Improvements in Water-Heating Agparatus, of which the following is a speci cation.

My invention relates to ap aratus for heatlng water, adaptable articularly for railway cars, and more especlally for private cars, so-called, or other railwayc cars which are likely to be cut off, frointhe steam su 1y provided by the locomotive or the station steam line.

The primary object of the invention is to provide a water heating apparatus, suitable for railwaycars of this general type, which will be relatively simple in its construction and will serve tomalntain a supply of hot water for wash basins or other fixtures available for immediate use, whether the car be connected. up or not with a locomotive or other source of supply of steam. i

The invention consists in the novel as rangei'nents, constructions and devices to be hereinafter described and claimed for carrying out the above stated objects, and such other incidental objects as will appear in the following description.

The invention is illustrated in a preferred embodiment in the accompanying drawings, wherein: v V

From this pipe leads a col water service pipe 15 provided with branch pipes 16, connected with cold water faucets or other fixtures requiring cold 1 water. Pipe 14 has a connection 17 leading to a steam heating device 18 (Figsfl, 5 and Gi aud 19, 19*, 19 1 Visa hot water service pipe provided with branch pipes 20 1eading to faucets or other'lixtures requiring hot water, the return end 19' o f -this circuit being connected by a T 21 witlip'i'pe 14 and the pipe connection 17 above. mentioned. This circuit includes, in addition to the pipes just mentioned, 'a pipe coil 22 and an expansion tank 2 3, The pipe coil 22 is arranged within an expansion tankfll connectd hlr es 26w' t w ter bac 2 of a -01? local heater 28 'appairatns she 11' in the drawings is intended :to be used particularly upon a private car, so called, and, the stove 28 in such case is a cooking range. Water is en plied to the water back 21 of the stove 28 from tanks 29 provided with a stand pipe 30 which would ordinarily extend through the roofof the car. The cold waterlpipe 15 is connected at 31, 31 l tanks 291 1;: endo Pip lfl tedwith the expansitint k W i f o P pe li r'i l ii ,check valve 32 being arranged in the pipe inadvance of the tanks.

The steam heatin device 18 consists pref erably of a cylindrical shell 35 on the ends of which are screwed heads 36, .37, into which are tapped the pipes 17, '13, respectively. A pipe 38, 38" leads from the train ipe 11 to and through the steam heating evice, the end of pipe section 38 passing loosely through the head 37 and being screwed into a boss 39 formed on the has 36. The head 37 is formed with a threaded boss 40. 7 Between this boss and the ipe 38 is arranged suitable packing 41, ield in place by follower 42 and nut 43. Screwed into the outer end of the boss 39 of head 36 is a ipe 44 which leads to the thermostat chain r 45 of the vapor regulator 46 which is arranged between pi e sections 38 and 38,

above mentioned; T is va or regulator, shown'in Figs. 7' and .8, may e oft esame 7 eral construction as that patented in petant to EgbertI-I. Gold, No. 7 71,628, dated October' 1964; and need not be described in detail. The vapor regulator serves to maintain the steam passing through the steam heating device at substantially atmospheric pressure; that is'to, say, steam from pipe 38 will pass through port 47 and hrough strainer 48 into pipe section 38",'s0 long as the thermostat 49 remains unexpanded, and valve 50 stands awa from its If steam is introduce into the heating device in greatervolume than can be contained therein, the excess passing through the'tlierinostat chamber throughpi e 44 will expand thermostat 49 and seat t e valve.

In an ordinary operationth'e port 47 of the vapor regulator is throttled to the extent neeess" ary re uired for the heater. r

peration: When the train pipe 11 o1 the ear is en plied with steam from a locomotive or 0 or source of supply; water forced from the tank 12 by air pressure supplied from the branch air line 13, is heated in the steam heating device 18 and circulates through the circuit 22 and pipe 19", expansion tank 23, and

'ipc 19". The water thus heated may be rawn oil or otherwise used at the fixtures (not shown) connected with branch pipes 20. Ifthere is no fire in stove 28, the water in passing through the coil 22 will heat or warm the water in tank 24. Pipe 15 supplies water from tank 12to the cold water faucets'or other fixtures connected with branch pipes 16. The same pipe supplies water to the tanks 29 which re lenish the water in tank '24 the water 'ack 27 of the stove. If the cards out 01f from the locomotive, a fire may be lighted in the stove 23. This will'heat the water in the water back 27,

roducing circiilation between the water ack and expansion tank 24. -Water in tank 24 will heat the water in coil 22, so that the fixtures associated with branchpipcs'20 are .and the steam heatin to maintain the amount of made up of pipe 19, coil these fixtures is kept in constant circulation whether it receives its heat from the steam heating device or from the expansion tank connected with the stove, so that hot water can be drawn at once from any of the aforementioned fixtures without waste. Preferably the discharge pipe 44 from the steam heating device passes around the tank 12, device itself with the steam pipe leadin t" 'ereto is located close to the tank 12; t e tank heater and associated pipe connections may be inclosed in an insulated box, the arrangement being generallsimilar to that described in my Patient 0. 1,249,518, granted December 11, 191

It will be obvious that the steam heating device and the stove may be used at the same time if found desirable. The vapor regulator serves to supply the water heater with just enough steam to keep the water at the desired tem erature. A certain amount of steam will a ways pass through the circuit formed by pipe 38", steam heater 1 8, and ipe 44, to keep the tank and associated parts inclosed within the box 52 from freezing;
